Why it works: Lemon and pepper match in chemistry and in kitchens. They rank in the top 3% of all ingredient pairs, and cooks put them together in 27,047 recipes. Both carry trans-2-nonenal, which smells cardboard, fatty. The science ↓
Boiled Fish with Hollandaise Sauce
Ingredients
Directions
Cook the fish
Wrap the pike in a cloth and place it over the fire to boil slowly until done, depending on the size of the fish.
Make the hollandaise
In a bowl, beat the butter until creamy.
Add the egg yolks, lemon juice, salt, and cayenne pepper to the butter.
Place the mixture in a saucepan over boiling water and beat with an egg beater until it thickens.
Gradually add the boiling water while continuing to beat until the sauce reaches the consistency of stiff custard, about 5 to 7 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Provides fat and richness, giving the sauce a smooth, creamy body.
- Egg yolks
- Emulsify with the butter and set when heated, thickening the sauce into a custard-like texture.
- Lemon juice
- Adds acidity that brightens the rich butter and balances the sauce.
- Pike
- Is the main protein, cooked gently by poaching so it stays moist and tender.
The step that matters
Gradually add the boiling water while beating. Egg yolks thicken when heated but can scramble if they get too hot or are added too fast. Adding the hot water slowly while beating keeps the sauce smooth and emulsified as it thickens.
